Question about RCA F32649 32" TV

Reflowed solder, replaced flyback - still have 5 "clicks" of deat

Hi,

I am trying to fix my inlaws F32649 32" TV. I am a budding arcade hobbiest from the world of cap kits. So, after the TV died, it just gives the "5 clicks" trying to switch on. I tried reflowing all the solder joints I could find on the boards. No help. I tried cleaning off as much of their disgusting nicotine dirt/stains. No Help. TV still gave the "5 clicks" of death. So, I read these boards, and decided the most likely cause was a bad flyback transformer.

Well, I finally got off my duff, tracked down the replacement part as a 244247, and replaced it. Went just fine. Everything flowed nice and silver and shiny.

Turned it on. "5 clicks" again. Argh.

I see no glow at all anywhere. No arcing. There's no sound. Nothing on the picture tube. After turning off, my discharge probe spikes up good to 15Kv or so (I haven't tried it on.)

My inlaws had various ways of describing how it failed originally. Space heater in front that wasn't there before. Then, screen going out. Possibly to a horizontal line? Not sure. Sometimes coming back on after turning off of a bit. But, after a day or so of that, nothing. Just the 5 clicks.

Any ideas? I'm game for using a multimeter and a soldering iron. I have a high voltage probe with banana clip for safe discharging. Many thanks in advance.

Thanks Ladywinn. I found the thyristor. Unfortunately, it was in great shape. In fact, on my board, it had a clip and adhesive to help hold it. (Factory installed clip and adhesive). Seems like they'd already tackled the thyristor issue on my model.

Picture on golden tee is dark red not normal green did revert to green but back to red


Sounds like a cold solder joint. Unless you have knowledge of electronics and high voltage, I wouldn't try to fix it myself. A honest TV repairman should be able to fix it. And when I mean high voltage, I mean 2000-3000 volts is average with a CRT TV tube.

Hd52w59 wont turn on


If you can get at it this set has a high voltage splitter up front (remove entire front grill beneath the screen and the inspection plate behind that) that also fails---it is usually tan in color and has a red HV lead coming from flyback to it---three wires there go to the picture tubes--just remove the one or two screws that secure it and look at the bottom for any burn marks or signs it has been arcing.

I have a Panasonic CT-36hL43G TV that just turned offf while watching it and now the led by the power button blinks one time. Can anyone tell me what this code means or what the problem might be?


i hope your tv is more than 4years old ....... in all CRT TV's or CRT monitors after 4years a component called flyback transformer (see picture ) becomes weak - its work is to supply voltage to tube............. then following are the signs ...
(1) in some TV's only front LED's blinks - no picture no sound.... (2) in some TV's picture comes slowly after few seconds or after few mins or after few hours......... (3) in some TV's suddenly picture & sound goes temporarly & after some time again it appears ...... etc in case of (2) & (3) only flyback transformer needs to be replaced .....100% GUARANTEE again TV works normallyBUT in case of (1)... --------------- YOUR CASE (a) either only flyback transformer gets deffective or (b) flyback transformer & another component called transister ( will be near flyback transformer & its back portion is attached to aluminium metal ) gets defective or (c) along with flyback & transistor -- 3 or 4 more components (resistors, diodes, some times ICs ) gets deffective so replacing flyback transistor is a must .. & to find whether any other component is deffective or not completemainboard has to be checked ....... so if you are a technical person & having expierence in servicing line then you can do it yourself otherwise approach good tv service engineer ........... your TV is really very good one ... so don't think of buying new TV .... just goahead for repairing it it is worth & it works for atleast 2 more yrs....... try this & tell me what happened switch off your TV ... remove power cord from socket ,,,,.ware some mat or chapples to your feet ..... remove your TV's back side cover ......... observe carefully for any physically damaged components .... if you find then don't do anything ... close tv cover & approach tv service engineer ............. but if no physically damaged components are visible then take a suitable screew driver & rotate 2 (or 3) Knobs on flyback transformer in clockwise or anticlockwise direction - very little ( 4 or 5 degrees ) - you have to do this without touching any cable or any part of your tv .......... then fix..... back side TV cover ........connect power cord - stay at a distance & switch on your tv ......... if you get picture atleast for few seconds then in your case only flyback transformer needs to be replaced otherwise complete mainboard has to be checked. to find other deffective component ............. so your tv problem is a harware problem - it cannot be solved using remote control or any buttons on your tv ..... if you are finding difficult to get it repaired then you can remove your tv mainboard with the help of some technician & send to me ...... i will replace deffective components .... & send back to you ....you only have to bare the shipping charges .....it will take maximum 12days (5days - to recieve + 2 days servicing + 5 days to send back to you )....

My convergence keep going out, I replaced the convergence twice. I have a rca hd52w59 modle


When you say replaced the convergence twice, are you refering to the convergence boards or the FL231 fuse? If its the FL231 fuse unless you replaced the DL231 and CL230 plus reflowed the solder on the flyback it will continue to keep blowing untill the 3 parts are replaced together and the flyback gets resoldered. If you replaced the convergence boards then try resoldering the flyback.

Xbox 360 no tv signal


Sounds like a problem with your graphics chip bud. Needs the solder joints underneath the graphics processor to be reflowed.

Most likely bad solder connections around the flyback area of the circuit board, that model is famous for bad solder around the flyback and bad flybacks them selves. But if the led doesnt flash 3 times then go out, its most likely a solder issue.

RCA 27V530T Powers up and plays perfect for about 5 min then shuts off

Tv shuts on and off by itself


This tv may have a defective flyback transformer . Your chassis # of this set indicates it is ctc197 . some of these sets also had weak caps in the power supply or loose connections in the horizontal section . If your set clicks like it is coming on then clicks right back off and does this a few times then i would say it is the flyback transformer . If not suspect the other circuits as your problem . A shop might charge between $80.00 to $120.00 to fix it . If you can't fix it , call around to get the best price . Good luck
